WRENCH.

SPECIFICATION forming part of Letters Patent N 0. 301,680, dated July 8, 1884.

Application filed April 7, 1884. (No model.)

To all whom it may concern..-

Be it known that we, JOHN H. Cons and Fannnnro L. Cons, citizens of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Wrenches; and we declare the following to be a description of our said invention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains toinake and use the same, reference being had to the accompanying drawings, which form a part of this specification,

This improvement relates tothat class of wrenches known as the Goes wrench, the object of the present invention being to attain a close and perfect-fitting thread upon the screw, while giving ample looseness for the movable jaw in its movement upon the bar; also, to render the construction of the parts such that the wrench can be manufactured with ease and facility.

Our invention consists in providing the movable jaw with a recess extending inward from the front, and inserting in said recess a threaded nut for engaging the rosette-screw, as hereinafter described.

In thedrawings, Figure l is a side view of a wrench embracing our invention. Fig. 2 is a vertical section of the movable jaw, looking toward the side. Fig. 3 is a vertical section of the jaw, looking toward the front, the screw and nut being shown therewith. Fig. 4 is a section of the jaw at line :1: ac. Fig. 2. Fig. 5 is a plan view of the nut, and Fig. 6 is a section of the nut for engaging the jaw and rosettescrew.

In referring to parts, A denotes the bar, having a head or stationary. jaw, A. B is the handle, G the ferrule or step, and D the rosette-screw, all of which may be of the usual form employed in the Goes wrench.

E denotes the movable jaw, which is made in the form indicated, with a recess, E, extending in from the front side through the cylindrical portion of said jaw and near the lower part thereof, but leaving an arm of metal, 6, below the recess of snfficient size and strength to work the jaw downward on the screw D. The opening at in this arm of metal is bored out to fit the outer diameter of the screw D, so as to move loosely thereon for guiding the Within the recess E is loosely fitted a nut,

I, of the form shown, which has a screwthread that engages the thread of the rosettescrew D with a good working lit, and so as to have asure hold thereon said not I is furnished with lips m m, that extend past the angles of the bar A and prevent the nut from revolving out of position. The front of the nut may be finished to conform to the front of the jaw E. The nut may be case-hardened. The recess E can be readily milled out in the jaw-casting by a rotating cutting-tool, so as to make the proper fit for the nut I. The screw D, working in the nut 1, effects the movement of the jaw E both up and down on the bar A Without the necessity of screw-threads in the jaw-casting, the arm 6 drawing the jaw down when the screw D is turned in, and when said screw is turned outward the nut I is forced against the shoulder at the top of the recess E for moving the jaw upward. Said shoulder also sustains the backward strain of the jaw againstthe nut I when the wrench is in use. This construction makes a very strong and serviceable wrench, and there is no liability of the jaw becoming worn and slipping on the threads of the screw.

What we claim as of our invention, and desire to secure by Letters Patent, is

l. The combination, with the bar and rosette-screw in a Goes wrench, of the jaw provided with the recess extending inward from the front of said jaw, the arm of metal below said recess bored out to receive said screw, and the threaded nut arranged within said recess and engaging the rosette-screw, substantially as set forth.

2. The nut I, provided with lips m m, in combination with the recessed jaw E, screw D, and bar A, substantially as and for the purpose set forth.

Witness our hands this 4th day of April, A. D. 1884.
